Mathematics is a vast and vibrant enterprise with theory at its core. It thrives today on its traditional interaction with the physical sciences and engineering, as well as the more recent connections to computing, information, and communication. It is increasingly inspired by emerging applications in fields as diverse as biology and finance.



Recent faculty honors include the INFORMS Young Research Prize, Itô Prize, Fulkerson Prize, PIMS Education Prize, Solomon Lefschetz Medal, and several Simons Fellowships.

The department’s Math Study Center provides a supportive and active learning environment for precalculus and calculus students. Graduate and advanced undergraduate students help them get unstuck, in a model that has since been adopted elsewhere.

Through the department’s Washington Experimental Mathematics Lab, faculty collaborate with graduate students, undergraduates, and community members on projects that are experimental, computational, and often visual, coming to understand mathematics as a creative discipline.

Department faculty, working with UW students and hundreds of contributors around the world, continue to develop SageMath, an open-source mathematical software project that seamlessly integrates various software packages into a common experience. In 2013, it received the Jenks Prize for Excellence in Software Engineering applied to Computer Algebra.


Undergraduate majors
(including ACMS majors)


The department offers an undergraduate degree program in Mathematics and an interdisciplinary program—joint with the Departments of Applied Mathematics, Computer Science & Engineering, and Statistics—in Applied and Computational Mathematical Sciences. The department is also a major service department, with over 15,000 students enrolled in its courses annually. The department received the University of Washington 2005 Brotman Award for Instructional Excellence.

Department faculty do fundamental research in classical fields of mathematics and lead the way in newer areas (see Areas of Research below). In addition to intrinsic mathematical research, they collaborate on interdisciplinary projects with Art + Art History + Design, Applied Mathematics, Statistics, Computer Science and Engineering, Bioengineering, Genome Sciences, Electrical Engineering, Mechanical Engineering, Physics, and the Applied Physics Laboratory. Some examples:

  • One faculty member has solved a longstanding open problem in the geometry of Riemannian manifolds, showing that knowledge of the distance function on the boundary determines distance overall. This work, featured in Nature, would allow one in principle to determine what is inside an object — the earth for instance — without destroying it.
  • Another recently discovered a formula for counting all tanglegrams of a given size. Tanglegrams are combinatorial objects that arise in subjects as varied as the study of cospeciation in biology and analysis of software projects in computer science.
  • In work with chemists at UW and beyond, a faculty member solved a probability problem about crystal deposits on a flat surface, thereby providing the theoretical justification for a procedure that may be used for cancer detection.
  • To develop a procedure for packing objects of different weights and sizes into the smallest number of boxes in the fastest time, a suitable algorithm will be slow and inefficient. One of our faculty made a major advance by finding an efficient algorithm producing solutions that, if not optimal, are demonstrably close to optimal ones.

Through Mathday, an annual event, more than 1,500 high school students visit the University for a day of engaging mathematics-related events led by Mathematics faculty and students.

Ongoing activities, such as a weekly after-school program for students who want to expand their mathematical horizons (UW Math Circle) and a weekend lecture series on the UW campus (Monthly Math Hour), introduce middle and junior high school students to the exciting world of mathematics.

The Summer Institute for Mathematics at the University of Washington is a privately funded summer program for talented high school students in the Pacific Northwest that introduces them to the depth and beauty of mathematics.
